Description

Technical Field

[0001] The utility model relates to the technical field of crushing equipment, in particular to a crushing cone body suitable for a cone crusher. Background Art

[0002] Cone crusher is a kind of crushing machine suitable for raw materials in metallurgy, construction, road construction, chemical and silicate industries. It mainly includes transmission device, eccentric sleeve, crushing cone and other structures. Among them, the crushing cone often includes fixed cone lining and movable cone lining, and a crushing chamber is formed between the fixed cone lining and the movable cone lining. When the cone crusher is working, the transmission device drives the eccentric sleeve to rotate under the action of the power source, and the movable cone lining rotates and swings under the force of the eccentric sleeve. When the movable cone lining approaches the fixed cone lining, the material in the crushing chamber is crushed by multiple squeezing and impact of the movable cone lining and the fixed cone lining. When the movable cone lining is away from the fixed cone lining, the material crushed to a preset particle size falls under the action of its own gravity and is discharged from the bottom of the cone.

[0003] Since the crushing surface between the moving cone liner and the fixed cone liner needs to form a preset crushing cavity, some moving cone liners and fixed cone liners may also need to be processed on the crushing surface (such as processing grooves) to increase the crushing efficiency, so the moving cone liner and fixed cone liner are usually set to steel to increase their machining performance. However, cone crushers are often used to crush materials with high hardness such as ore. Steel is easily worn under the action of ore, which deteriorates its processing effect and even has the risk of material jamming, affecting the service life of the moving cone liner and fixed cone liner.

[0004] Therefore, it is urgent for those skilled in the art to provide a crushing cone that can meet the machining performance and has high wear resistance to ensure its service life. Summary of the invention

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] See also Figures 1 to 9 The embodiment of the utility model provides a crushing cone suitable for a cone crusher, including a liner assembly 1, the liner assembly 1 having a crushing surface 10; a wear-resistant part 2 is enclosed in the liner assembly 1, and the wear-resistant part 2 is arranged close to the crushing surface 10, and the wear resistance of the wear-resistant part 2 is greater than that of the liner assembly 1. On the one hand, the machining performance of the liner assembly 1 can be improved, and on the other hand, by enclosing the wear-resistant part 2 in the liner assembly 1, the wear resistance of the liner assembly 1 can be increased, thereby increasing the service life of the liner assembly 1.

[0034] Specifically, see Figure 1 and Figure 2In this embodiment, the liner assembly 1 includes a movable cone liner 11 and a fixed cone liner 12 which are arranged in a split manner, a crushing chamber 13 is formed between the movable cone liner 11 and the fixed cone liner 12, and the crushing surface 10 located on the movable cone liner 11 and the crushing surface 10 located on the fixed cone liner 12 form the inner wall surface of the crushing chamber 13. Wear-resistant parts 2 are fixedly arranged in the movable cone liner 11 and the fixed cone liner 12, and the wear-resistant parts 2 located in the movable cone liner 11 and the fixed cone liner 12 are arranged close to the crushing chamber 13. Of course, in other embodiments, the wear-resistant parts 2 can also be arranged only on the movable cone liner 11 or only on the fixed cone liner 12.

[0035] The number, location, and distribution of the wear-resistant parts 2 on the moving cone liner 11 and the fixed cone liner 12 can be set in various ways, so that the wear-resistant parts 2 can continue to extrude materials when the moving cone liner 11 and the fixed cone liner 12 are worn.

[0036] See also Figures 3 to 6 , taking the movable cone liner 11 as an example for explanation, in this embodiment, the movable cone liner 11 of the liner assembly 1 is formed by casting and solidifying molten steel. Along the axial direction of the crushing vertebra, the wear-resistant parts 2 on the movable cone liner 11 are distributed in two layers, and each layer of wear-resistant parts 2 is distributed in a circumferential array. A casting spacing 3 for accommodating molten steel so that the molten steel is solidified to form steel is formed between two adjacent wear-resistant parts 2. During the casting process of the movable cone liner 11, the molten steel can be solidified within the casting spacing 3, thereby increasing the connection area between the movable cone liner 11 and the wear-resistant parts 2, so as to increase the stability of the installation of the wear-resistant parts 2 and prevent the wear-resistant parts 2 from falling off during the contact with the material.

[0037] Furthermore, since the molten steel will shrink to a certain extent during the solidification process, in order to increase the stability of the connection between the two adjacent layers of wear-resistant parts 2, the two adjacent layers of wear-resistant parts 2 can support each other in the axial direction, and the two layers of wear-resistant parts 2 are staggered. Of course, in other embodiments, the wear-resistant parts 2 can also be arranged in three, four or more layers.

[0038] Furthermore, the ratio of the maximum width W1 of the casting interval 3 to the maximum length L1 of the wear-resistant part 2 can be set to 0.2, 0.25 or 0.3, so that the steel filled in the casting interval 3 can be stably connected with the wear-resistant part 2, thereby achieving a stable connection of the wear-resistant part 2. Of course, in other embodiments, the maximum width of the casting interval 3 can be set to 25mm, 27.5mm or 30mm, and the maximum width of the wear-resistant part 2 can be set to 110mm, 115mm or 120mm.

[0039] Furthermore, in order to increase the contact area between the wear-resistant part 2 and the material, in this embodiment, the wear-resistant part 2 is set to be plate-shaped and has a relatively parallel first plane 21 and a second plane 22, wherein the first plane 21 is located on the side of the second plane 22 close to the crushing surface 10 and is parallel to the crushing surface 10. The distance S1 between the first plane 21 and the second plane 22 can be set to 10mm, 15mm or 20mm, and the distance S2 between the first plane 21 and the crushing surface 10 can be set to 20mm, 22.5mm or 25mm.

[0040] See also Figure 3 The movable cone liner 11 is provided with a first accommodation area 111 for accommodating the wear-resistant part 2. In the axial direction of the crushing cone, the ratio of the height H1 of the first accommodation area 111 to the height H11 of the movable cone liner 11 can be set to 0.25, 0.3 or 0.35. The ratio of the distance H10 from the upper end of the first accommodation area 111 to the bottom of the movable cone liner 11 to the height H11 of the movable cone liner 11 is in the range of 0.4, 0.5 or 0.6.

[0041] See also Figures 7 to 9 , which is the same as the wear-resistant parts 2 arranged on the moving cone liner 11. In this embodiment, in order to increase the stability of the connection between the fixed cone liner 12 and the wear-resistant parts 2 located thereon, the fixed cone liner 12 of the liner assembly 1 is formed by casting and solidifying molten steel. Along the axial direction of the crushing vertebra, the wear-resistant parts 2 on the fixed cone liner 12 are distributed in two layers, and each layer of wear-resistant parts 2 is distributed in a circumferential array, and a casting spacing 3 for accommodating molten steel so that the molten steel is solidified to form steel is also formed between two adjacent wear-resistant parts 2; the wear-resistant parts 2 of the two adjacent layers located on the fixed cone liner 12 are staggered.

[0042] It can be known that in order to increase the stability of the installation of the wear-resistant part 2, the size of the casting spacing 3 on the fixed cone liner 12, the size of the wear-resistant part 2, and the proportional relationship between the casting spacing 3 and the wear-resistant part 2 can all be consistent with the arrangement on the movable cone liner 11, and can be adjusted according to actual conditions. Therefore, no further description is given.

[0043] In order to arrange the wear-resistant parts 2 on the fixed cone liner 12 opposite to the wear-resistant parts 2 arranged on the movable cone liner 11 so that the two can cooperate with each other to realize the extrusion of materials, in this embodiment, a second accommodating area 121 for accommodating the wear-resistant parts 2 is provided on the fixed cone liner 12; along the axial direction of the crushing cone, the ratio of the height H2 of the second accommodating area 121 to the height H12 of the fixed cone liner 12 is set to 0.25, 0.3 or 0.35.

[0044] Furthermore, the distance S3 from the lower end of the second accommodating area 121 to the bottom of the concave liner 12 can be set to 10 mm, 15 mm or 20 mm.

[0045] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
